The present invention relates to methods for producing metal-supported thin layer skeletal catalyst structures, to methods for producing catalyst support structures without separately applying an intermediate washcoat layer, and to novel catalyst compositions produced by these methods. Catalyst precursors may be interdiffused with the underlying metal support then activated to create catalytically active skeletal alloy surfaces. The resulting metal-anchored skeletal layers provide increased conversion per geometric area compared to conversions from other types of supported alloy catalysts of similar bulk compositions, and provide resistance to activity loss when used under severe on-stream conditions. Particular compositions of the metal-supported skeletal catalyst alloy structures can be used for conventional steam methane reforming to produce syngas from natural gas and steam, for hydrodeoxygenation of pyrolysis bio-oils, and for other metal-catalyzed reactions inter alia.

A method of producing normally solid, normally liquid and optionally normally gaseous hydrocarbons involves contacting a gas mixture comprising hydrogen and carbon monoxide with a catalyst under elevated temperature and pressure, to convert at least part of the hydrogen and carbon monoxide into hydrocarbons. An effluent is withdrawn from the reactor and subjected to a separation step to form at least a heavy fraction and a light fraction. The heavy fraction comprises normally solid hydrocarbons, while the light fraction comprises unconverted syngas and normally liquid and optionally normally gaseous hydrocarbons. The light fraction is sent to a light ends stripper operating at a temperature of maximally 200 C. to obtain a hydrocarbons fraction comprising normally liquid hydrocarbons. The heavy fraction is subjected to flash evaporation or steam stripping to obtain a hydrocarbon stream of normally solid hydrocarbons (comprising mainly C10+ hydrocarbons).
